Cityscapes classes IoU 0.802 train from scratch or use pretrained model?

[binzh93]

Hello,
I find pretrained model is not included in cityspcae yaml file.Is the best result training from scratch? Or use the the model convert from tenosrflow imagenet pretrained model, I find in your training code:

pytorch-segmentation/src/train.py

Line 113 in ddf7ce9

if pretrained_path:

when you load the pretrained model, the model network includes some layers not in xception65. Is your loading model converting from tenosrflow cityspace pretrained model, or training from scratch?
look froward to you reply, thanks
